Investigation & Keeper Notes Management
Codex Cryptica for Call of Cthulhu
Keep Investigators, contacts, handouts, clues, cults, and tomes connected in one local-first workspace.
Why campaigns get complicated
Call of Cthulhu scenarios quickly develop into webs of open leads, witness testimonies, physical handouts, and occult conspiracies across multiple sessions. When your Investigators follow a trail back to an archive or re-interview a local coroner weeks later, you shouldn't have to scramble through scattered notes to recall which clue led them there, what they uncovered, or which leads remain unresolved.
Why Codex Cryptica?

Occult Tomes, Handouts & Lore
Link newspaper clippings, letters, translated manuscripts, and occult relics directly to the people, locations, and clues they reveal.
Events, Timelines & Keeper Notes
Track chronological events, escalating scenario countdowns, active Investigator leads, and Keeper session notes in one connected workspace.
